To adjust the torque on these screwdrivers. Proceed as follows:
1.
Determine the torque output of the tool by checking a tightened fastener with a torque wrench.
2.
Increase or decrease the torque by turning the torque adjusting nut on the nose of the driver. Turning the nut clockwise to a
higher number on the torque scale increase torque output while rotating the nut counterclockwise to a lower number decreases
the torque output.
3.
Check the adjustment with a torque wrench. A number of factors will affect torque output from one job to another. Final torque
adjustment should be made at the job through a series of gradual increase. Always start below the desired torque and work
upward.
4.
Adjust the bit torque by changing the driving in length of the adjust nut at the end.
5.
The relationship between torque scale on nut and bit torque is as shown in the torque diagram. The figures of torque scale do not
indicate bit torque actual values. However, the clamping torque of screw itself is different form type, size, material of the screw
and the material of its mating part. Use it as standard to obtain an appropriate clamping torque.
6.
The (Return torque method) in which once-clamped screw is returned with torque wrench or the like is available as one of torque
control methods however, note that the measured values by the return torque method generally appear in 10%~30% lower than
the actually clamping torque.
7.
The torque tester measures the torque of screwdriver. The clamping torque of screw itself is different from the clamped
conditions. Understand the correlation between clamping torque values and the torque tester values perform the torque control
properly.
1.
Also in reverse rotation, the clutch is shut-off in such manner as in normal rotation, stopping the motor running accordingly,
when the screw tightened at a large torque, set it to a higher torque scale.
2.
The numbers from zero to eight on the torque scale are reference number only and not an indication of actual torque output.
